Mao you need to learn that all the people on here are experts and know everything, don't bother arguing with them.

You will never win!!!!

Mao i appologise, i am not trying to argue. Just learn.

You're wrong there. People will jump on unfounded and impossible to prove comments just to flog your product. Any other comment wouldn't have received any attention.

And let's be honest. Especially when you compare these unjustifiable comments against a house favourite in Verso.

365hp and 515nm

New Beast to arrive April 2015 - 365hp, 450nm, 0-100 in 4.4sec. AMG Goodness!

Tuning and dyno numbers aside, the ViPec is a good unit. Better than a reflash at a standard WRX level? Questionable & everyone has their own opinion. But you do get Antifag, which is full of win. I am sure you could spend the money that you would have spent on a ECU on worse things.

I think if you plan to do major work to your car, the unit leaves re-flashing / open source way behind. I am far from being an expert but I know that with my current build, the standard ECU would not work.

I have been told you can run dual fuel / ignition maps by switch control, trigger electrics such as inter cooler spray at a set boost pressure, going off your MAP sensor. I am sure there are many other uses for these digital / analogue inputs and outputs, if you have time to think about what you can do with them.

People spend a grand + on the 2 most well known Open Source tunes. 1 of those tuning methods is not well liked on here, it begins with an E. Has anyone ever heard anything bad about the ViPec ECU? I say its pretty good value for money for a intermediate mod level, daily driven car.

Each to their own though & as said before, people have a right to their own opinion.

I agree that Mao's post is probably unfounded, but why do these threads have to turn to shit all the time.

Seems to be common these days, good threads head South

Why didn't the vendor with the fraudulent GB cop anywhere near as much shit as this..............

1) There are vast differences between a open source tune other than just datalogging. You dont even get a map trace on most of the popular softwares.

2) You can tell how much hp a car makes with mph? You are a legend.

Based my opinion on the WOT power and torque runs of both cars done on our dyno.

Yes 2 different ecus, 2 complete different drivers, 2 different GDs, Simon's 2.0 STi and the other a 2.5 STi.

All good Russ, have a good weekend.

We have just re-tuned Simon's car ready for his round of 0-400m today. Couple of months back, the car had a misfire above 5000rpm where we reset trigger levels on the Vi-pec to dismiss the tune. This resulted in a 335hp run.

However, at the last Kwinana drags, he complained of a misfire up top again which only gave him a best time of 12.7s.

Yesterday, we put his car on the Dynapack for a retune. This time round, the car hit 330hp max. After about 3 runs, the car started misfiring again, dropping power to 308hp. We tried to reset voltages and dwells, as well as trigger levels, but there was no improvement.

We then proceeded to change the Ik22 plugs and new coil-packs. Problems solved!! You can see these products at our Spark plugs thread ( http://www.perth-wrx.com/vb/evolutio...ark-plugs.html ) and O2/Coilpack thread ( http://www.perth-wrx.com/vb/evolutio...l-packs-2.html. )

Below are pics of 2 of the coil-packs taken off Simon's engine:



New Coil pack we put in:


Below is how Roughstilin's car performs when it misfires:


Below is the result of today's tune and our tune is health-proven. Stock STi 2.0 engine is still mint, producing awesome power boosting at a max of 1.85 bar of boost after all the events he has been to.

Awhile ago, we had the chance to work on a WRX with an STi conversion including DCCD running a twin scroll VF36:
http://www.perth-wrx.com/vb/evolutio...07-wrex-2.html

The car has since changed hands and the new owner had installed a HKS GT2835 and below are the 2 tunes we did.

On the first tune, it hit a max of 290.5hp before the HKS turbo bearings were damaged. The HKS turbine was bought as a used unit which was claimed to have been rebuilt only recently with very little kms done on it. The other thing queried was what engine oil was used and it was apparently Mobil 1 which made me quite skeptical.

First tune before turbo blew which hit 290.5hp compare with the 322hp result on the
2nd tune with overhauled HKS Turbo:


So regardless whether it was a worn turbine or bad engine oil, this P.WRX member quickly repaired the turbo via Turbotech and brought the vehicle in for the second tune --- this time using Cusco Engine oil.

Below is the final tune at 322hp in comparison to 269hp when it was using the VF36. (Torque could have been smoother, but unfortunately with a 35degC workshop temp, we were not going to push more timing.)
